IMPROVEMENT IN HEATING-STOVES.

Specification forming part of Letters Patent No. l 80,592, dated August 1, 1876; application filed June 28,1876.

To all 'whom it may concern: y

Be it known that I, PHILIP OscAR JEN KINS, of the town of Gilman, in the county of stoves, where fines for the outlet of smoke or otherproducts of combustion are wanting, and

where the healthiest form of heat is desirable.

In the perspective drawing, Figure l, a represents a platform, made ofwood or metal, (when of wood to be covered with roll-zinc.) b b represent two upright pieces, firmly inserted into the platform, and fastened by a screw-tap on its under side. On the top of these two upright pieces, which I may call supporters,77 the cylinder of the stove is mounted by two pivots inserted in a band begirting it. These pivots are seen at C. This stove-cylinder, made of any suitable material, is made without any door, and without any draft arrangement, and is closed up at its bottom like a bucket. Its lid is without hinges, or their equivalent, for the greater convenience, it being made after the fashion and used as would be the lid of a tin bucket. The stovecylinder is suspended a little above the platform, so that it may have'no impediment to its being turned on its pivotal axis when sodesired. D is a small pipe, which communicates with the interior of the stove at E. Attached to this pipe are two hooks to hold by a bail the small bucket F, into which the lower eX- tremity of the pipe (open at its end) dips. The

two strips GG, lying across the platform and under the stovecylinder, and which are at their ends bent in opposite directions at right angles with their body, are made by a notch in them to lock together, and thus act as one piece, as seen in drawing, to hold the stovecylinder in its place, except when otherwise desired, when they are easily removed.

Fig. 2 represents a perspective view of the interior device of the stove. His a bucket, fitting snuglyinto the top of the stove, and is intended to be of sufficient capacity to hold an amount of water necessary to slake the lime below it. This bucket has a stout bail or handle placed in the inside J, and is intended for lifting it from its place when desired.l To its bottom is attached a small hollow cylinder, H. This cylinder is-open at its attachment or junction, where there is also a hole in the bottom.

of the bucket. This tube dips wedge-like into another hollow cylinder at K, which thus forms a continuons canal from the bucket to the bottom of this cylinder, which reaches to the bottom of the stove, where its bottom is closed to hold water. In the bottom of this bucket, and around the descending small cylinder, are numerous small holes, at proper intervals. I is a fender, of rods, designed to protect the small cylinder within it from im mediate contact with the pieces of lime to be slaked. L is a ring, of iron or other metal, of sufficient thickness for strength, and of corresponding width. It is made to t the bottom of the stove-cylinder, is elevated about one-half inch above it, and has a notch cut in the inside, so as to let down the fender through it by arms attached to its rim at P, and turning the fender. After these arms slip in and below the ring, the fender is turned to the left, and the arms attached to the rim are checked yby pieces p, fastened on its Linder side. This arrangement keeps the fender in its place till desired to be taken out, when, by reversing the turning till the arms come back to the notches in the ring, it is easily removed. Q Q are rims, to which the rods composing the fender are attached. O O O are pieces or strips connected to the fender by three arm-pieces attached to the rim Q, and are intended to keep the fender and its inclosed small cylinder in their place Ain the center of the stove.

Fig. 3, m is a mallet, of about two and onehalf inches diameter, and is made of solid in dia-rubber. A sack, which it is not deemed necessary to showin drawing, is made of closetextured goods, as oilcloth, armed at its mouth with a stout india-rubber band, or a strip of leather with a buckle, to bring it tight and close around the top of the stove when needed for removing the lime. t will be seen, in describing the mode of using the stove, that this is an important appendage.

'Mode of using the invention: Having removed the top or lid ofthe stove, and displaced the bucket from Within, pieces of lime, of convenient size for handling, are placed around the fender of rods until it contains about what would be one-third the amount it would hold, making allowance for the space taken up by the fender. Fill the small bucket attached to the pipe with cold Water; replace the large bucket in the stove, pressing slightly, so as to secure its connection,- by its short cylinder, with the cylinder below. Then pour in as much Water, by Weight, as will be one-third the Weight ofthe limc into this bucket; place on the lid of the stove, and the Work of slaking and the consequent evolution of heat begins,

and will rapidly develop till it reaches its maximum height, which varies in the ratio of the amount of lime slaked, and the gradual and uniform mode of doing it. A stove of large capacity, in using my device, will develop a heat of near 1,0000. rlhe mere pouring on of the Water would not gain the amount of heat desired; but, as in my process, the water falling down in fine drops through the holes in the bucket, and then being forced in small sprinkles from the small holes in the cylinder connecting at right angles with it, the mass of the lime receives the water gradually in the center, while the top of the mass is slowly Wet by the fine drippings or sprinkling from the bucket, and thus a uniform and gradual slaking secures its highest degree of heat. The

`will bring all the lime into the sack.

steam which may be evolved and the gas (when present) are both received in the small bucket of Water at the end of the pipe. The former becomes condensed and becomes Water, and the latter is absorbed.

The stove being so constructed that its cylinder can be lifted oli' from its place on the upright supporters, as shown, more than one cylinder can be used when desired, one being removed for a fresh one freshly charged with lime. The plan, however, of emptying the lime by the use lof the sack described is better. rlhis is done by placing the india-rubberbanded mouth ofthe sack, or the leather and buckle arrangement, ifpreferred, and hugging the stove closely, you remove the hooks that confine the stove, and turn the stove upside down; then take the mallet m, Fig. 3, and give the stove a few slight taps, and the jar it gets The sack is then removed from the stove Without getting any lime in the room.

I claim as my invention- 1. The combination of the platform a b b G G with the stove-cylinder, pivoted and adapted to operate substantially as shown and described.

2. The combination, with the body of the stove, of the pipe D and bucket F.

3. The combination, with the outer containing-cylinder, of the interior bucket H, perforatedtube H', and protecting-rods I.
